Find the perimeter of the quadrilateral beolw. (x2 - 7x + 9) units
(x2 - 7x + 9)
units
4x2 - 28x + 36 units
2x2 – 14x + 18 units
4 14x2 + 18 units
O x4 – 28x2 + 36 units

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
